Abstract
In recent years, a number of advanced linear induction accelerators (LIAs) have been developed which have the capability for accelerating very high beam currents, provided that satisfactory answers are obtained to a number of beam transport and stability issues. Examples of this new technology include the advanced technology accelerator (ATA), the RADLAC accelerators, and the LIU accelerators of the Soviet Union. In this review we analyze several important beam transport issues pertaining to the propagation of very high current electron beams in and through the accelerating structures. In particular, we develop criteria for various equilibrium configurations, injector designs for producing the equilibria, general beam stability criteria, zero-order analyses of accelerating gap designs and considerations of various multiple-gap instabilities, including transverse beam break up and image displacement. We also briefly describe the new transport technique of ion channel guiding. Finally, we analyze the special problems associated with transporting high current ion beams (protons) through such linacs.
